Researchers have made significant breakthroughs in producing an anti-COVID-19 stainless steel that kills the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) on its surface. The anti-COVID-19 stainless steel can also inactivate the H1N1 virus and E.coli on its surface.

Stainless steel is one of the most extensively used materials in many public areas and hygiene facilities but has no inherent antimicrobial properties. Additionally, the SARS-CoV-2 exhibits strong stability on regular stainless-steel surfaces, with viable viruses detected even after three days.

The inactivation of pathogen microbes (especially the SARS-CoV-2) on a stainless-steel surface is achieved by tuning the chemical composition and microstructure of regular stainless steel. The breakthrough also found interesting points about Ag and Cu as the allying elements to prepare anti-pathogen the stainless steel.
